Description

Technical Field

[0001] The utility model relates to the field of household appliances, in particular to a lighting device. Background Art

[0002] When performing long-term and intense visual tasks such as working, reading, and studying, the brightness and uniformity of the light on the work surface have a greater impact on eye health. When the light brightness is appropriate, the more uniform the light distribution, the more comfortable the visual experience. However, most families rarely pay attention to matching the indoor lights with the workbench when decorating the room. This may result in low uniformity of light on the work surface of the workbench due to indoor lights, and additional lamps are needed to improve the light uniformity of the work surface to reduce the visual burden.

[0003] When lamps are used as the primary light source for visual tasks, the contrast between the indoor ambient light and the work surface is stark, causing pupils to constantly adjust in size, which can easily lead to visual fatigue. This necessitates the use of additional light sources to increase the brightness of the indoor environment. Furthermore, when using electronic products in dim environments, the stark contrast between the screen brightness and the ambient brightness significantly impacts vision. This is especially true today, as many users use electronic products before retiring at night, requiring additional ambient light. However, high ambient brightness can easily disrupt sleep. Furthermore, most lamps project light downward, placing the light-emitting portion of the lamp directly within the user's field of vision when using electronic products while lying on their back or side, potentially irritating the eyes.

[0004] Currently, there are floor-standing lamps on the market that project light downward, parallel to the work surface, to improve lighting uniformity. There are also top-lit lamps that project light toward the ceiling, allowing the light to diffuse through the ceiling and spread throughout the room, softening the illumination. However, most of these lamps have fixed angles and directions, providing good results but limited functionality. Users must purchase multiple lamps based on their needs, each of which needs to be turned on and off individually. Rotatable lamps can adapt to various usage scenarios by adjusting the angle and direction of the lamp. However, after rotating most lamps, users find it difficult to adjust them back to a position parallel to the work surface, which can affect the lighting uniformity of the work surface. Utility Model Content

[0006] Another advantage of the present invention is that it provides a rotatable adjustable lighting device, wherein the rotatable adjustable lighting device can change the direction and angle of the outwardly projected light to meet the user's different needs for ambient brightness. In this way, after the user leaves the original position, the user can adjust the position of the light projected by the rotatable adjustable lighting device accordingly to obtain the appropriate ambient brightness.

[0007] Another advantage of the present invention is that it provides a rotatable adjustable lighting device, wherein the rotatable adjustable lighting device is provided with an ambient lighting mechanism and a task lighting mechanism, and the ambient lighting mechanism and the task lighting mechanism are easy to disassemble separately, thereby facilitating the separate packaging of the ambient lighting mechanism and the task lighting mechanism, thereby reducing the packaging area and lowering the transportation and storage costs.

[0008] Another advantage of the present invention is that it provides a rotatable adjustable lighting device, wherein the rotatable adjustable lighting device can separately control the ambient lighting mechanism and the task lighting mechanism, so that the user can improve the light uniformity of the work surface and / or improve the ambient brightness according to their own needs.

[0009] Another advantage of the present invention is that it provides a rotatable and adjustable lighting device, wherein the ambient lighting mechanism can rotate horizontally and axially relative to the task lighting mechanism, so that after the user fixes the light-emitting surface of the task lighting mechanism to project light downward in a state parallel to the task surface, the ambient lighting mechanism can adjust the position of the projected light by horizontal rotation and / or axial rotation to obtain appropriate ambient brightness.

[0010] Another advantage of the present invention is that it provides a rotatable and adjustable lighting device, wherein the electrical connection between the ambient lighting mechanism and the task lighting mechanism is easy to disconnect, so as to facilitate the assembly of the separately packaged ambient lighting mechanism and the task lighting mechanism.

[0011] Another advantage of the present invention is that it provides a rotatable and adjustable lighting device, wherein the lamp beads of the ambient lighting mechanism are configured as a hidden design to soften the light that increases the ambient brightness and prevent the light projected by the ambient lighting mechanism from directly entering the user's field of vision and stimulating the vision.

[0012] Another advantage of the present invention is that it provides a rotatable and adjustable lighting device, wherein the task lighting mechanism is configured to diffuse a linear light source to a surface light source, and the surface light source projects light onto the task surface in a direction parallel to the task surface with its light-emitting surface, so that the task surface maintains a high degree of light uniformity.

[0054] Specifically, the fixing member 13 includes a first fixing portion 131 and a second fixing portion 132. The first fixing portion 131 extends obliquely upward from the end of the second fixing portion 132. The end of the second fixing portion 132 away from the first fixing portion 131 is defined as a horizontal fixed end, and the end of the first fixing portion 131 away from the second fixing portion 132 is defined as an inclined fixed end.

Specifically, the rotating assembly 12 also includes an upper limit bearing seat 123, a lower limit bearing seat 124 and a second rotating bearing 125. The second rotating bearing 125 is located between the upper limit bearing seat 123 and the lower limit bearing seat 124.

[0062] In addition, a limit can be set for the rotation angle of the ambient lighting mechanism 10. Specifically, the rotating assembly 12 includes an upper limit bearing seat 123 and a lower limit bearing seat 124. The outer end of the upper limit bearing seat 123 is fixed to the task lighting mechanism 20, and the lower limit bearing seat 124 is fixed to the rotating bearing seat 121 and rotates with the rotating bearing seat 121.
